12 Claims.

This invention relates to machines for makin insoles and is herein illustrated as embodied in mechanism for assembling insole blanks and ribbed canvas material.

In United States Letters Patent No. 2,538,776. granted January 23, 1951, in the name of Stanley M. Griswold, there is disclosed a method of making paired insoles for welt work.- In carrying out the method, use is made of an insole-- shaped matrix having a groove in each of its opposite faces corresponding in outline to the rib of one of a pair of insoles. The matrix is covered on each side with an all over layer of canvas or Gem duck cemented on its outer face and the canvas is tucked into the grooves to form ribs after which insole blanks or body layers similarly coated are located upon each side of the matrix with the cemented sides toward the cemented side of the canvas layers and the whole assembly is subjected to pressure to cause the insole blanks to become firmly bonded to the canvas.

It is an object of the present invention to provide mechanism for quickly gaging or spotting insole blanks in accurate relation to the canvas layers positioned upon opposite faces of a matrix.

To this end, and as illustrated, the mechanism comprises a support for a matrix and two leaves pivotally mounted upon opposite sides of the Fig. 5 is a cross sectional view taken along line v-v of Fig. 3;

. line VII-VII of Fig. 3.

The mechanism herein illustrated is adapted to carrying out in part the method of making insoles disclosed in the aforementioned Griswold Letter Patent. To that end, means hereinafter described are provided for locating two insole blanks or body portions Hl, Fig. 1, in alinement with a matrix 12, opposite faces of which are covered with pieces of canvas 14, contiguous surfaces of the canvas and blanks having been precoated with adhesive, and thereafter applying pressure to the matrix and blanks to secure the body portions I0 and canvas pieces M together in assembled relation as shown in Fig. 2.

The spotting mechanism is mounted upon a bracket [6 extending from the upper portion of 7; supports being carried by the bracket 16 and support and having means for supporting insole blanks, together with power operated means for closing the leaves. Preferably, and as shown, the leaves have blank retaining means which are retractable upon movement of the leaves toward the matrix thereby to permit close approach of the blanks to the matrix. Preferably, too, the matrix support is movable in a direction heightwise of the leaves in order to engage a tripping device for initiating an operation of power operated mechanism for closing the leaves.

These and other features of the invention are disclosed in the following specification and in the accompanying drawings and are pointed ou in the claims.

In the drawings,

Fig. 1 is a perspective view of the upper portion of an insole pressing machine provided with insole spotting or gaging mechanism constructed in accordance with the invention;

Fig 2 is a perspective view of a matrix with two insole blanks positioned thereon;

Fig. 3 is a side view, partly in section, of the spotting mechanism shown in Fig. 1;

Fig. 4 is a view in front elevation of the spotting mechanism;

two leaves 26 pivotally mounted on the bracket upon opposite sides of the matrix for angular movement relatively thereto.

The matrix supports are in the form of plates extending in a vertical plane and have upon their upper edges'ribs 28 constructed and arranged to enter a circumferential groove 30 in .a matrix when the latter is positioned upon the supports.

Means are provided for adjusting the supports 22 and 24 heightwise of the bracket IE. To that end the support 22 has a depending portion 32, Figs; 3 and 5, slidablymounted in gibs 34 secured by screws 35 tothe bracket IS. The lower end of the portion 32 has a lateral flange 36 receiving an adjusting-screw 38 rotatably mounted in a plate All secured to the gibs by screws 42. Adjustment of the supportheightwise of the bracket I5 is obtained upon rotation of the screw 38. A spring 44, Fig. 4, between a knurled nut 46 on the screw and the plate 4!] acts to retain the support in adjusted position.

The means for adjusting the position of the support 24 comprises a slide 48, Fig. 6, mounted in gibs 50. The slide 48 is arranged slidably to receive a depending portion 52 of the support 24, adjustment'of the support being accomplished by a screw 54 having a knurled head 55, Fig. 3, and rotatably mounted, against pressure of a spring 51, in a plate 56 secured to the slide by screws 58. The slide 48 is yieldingly retained in its uppermost position by a spring 50 extending from a pin 62 on the lower portion of the slide to a pin 64 on one of the gibs 50. This construction while providing adjustment of the matrix support 24 also provides for a slight downward movement .of the support 'an'd .slide 48 to initiate operation of the 'leaves26' as will be hereinafter described.

It is to be noted that the bracket I6 is tilted;

forwardly and downwardly at an anglemfiabout 30 to the horizontal, Fig. 3, thus to present the matrix supports 22 and 2 1- and the leaves 26 in a convenient position for-insertion "'ofx't'he work. A matrix, when located upon the'supports;

will be located laterally byiztheiribszi'fi. .:;It.:..is held in a predetermined position along the supports by the action of gravity forcing it-against a stop 65 having a shank 68 which is slidably mounted in a bracket '10,'Fig. 4 ,secured by-screws 12 to an upwardly extending portion 14-of the bracket IS. The bracket carries-ways 16- engaging the shank 68, and therexis a stop'adiusting screw lilhavin a-imurled head l9 and rotatably mounted, against pressure of' a spring '81,

96, Fig; '7, extending longitudinally of'ea'chde'af.

and secured thereto by screws 98.

In order to facilitate-positioninginsole-blanks upon the abutments and f-or-retaining the blanks on the leaves during-initial -movement. thereof toward the matrixeach'leaf isprovided with'tworetaining members lilo-located near opposite-ends of the leaf. Eachmember is in the form :of Va U-shaped plate, one --leg 102-of-which is slidably mounted in gibs-l04 SBCUIYGditOthG-Olltfil face of the leaf by screws I05. plate extends through an opening I08 in thelea'f and. has an upstanding leg N0 of suflicient length normally to extend above'the upper face of the abutment 96 when the leaves 26 are in open position ;as shown in full'lines in Fig; 4. "'lnthisrposition the leg H0 acts as' aguideforpositioning-and retaining a blank on therabutment.

To effect withdrawal of the retaining members I09 when the leaves approach the-xmatrixf'the plate N12 is caused to be-moved-id'ownwardly' by means of a 1ink'112 having-onezend.pivotally mounted upon the plate -at"! l4 and having 'rits other end pivoted-at H6 toa bracket .118 secured to the bracket I B.

For locating insole blanks lengthwise of'. the leaves 26' there areprovidedabutments 1'20; Fig. 4, secured by screws I22.:to-:thei inner:;faces of the leaves. These abutments extend substantially at right angles toabutmentBGxand are'arranged to engage the heel end portion of anrinsole blank.

The means for applying-pressuretothe :blanks upon closing the leaves with the-matrixaand blanks in alinement comprises-stiff..leafnsprings I24 positioned inz-grooves l-26:iin.;the' upper-p01.-

tions of the inner faces of the leaves 26, the springs being secured at their outer ends to the leaves by rivets i28. This construction is such that when the leaves are closed the springs I25 exert'pressure over a limited area only of the insole blanks in effecting a bonding of the blanks to-' the matrix sufficient' temporarily to secure the blanks in position with their edge portion in predetermined approximate alinement with the --'edges of the matrix. The upper edges of the wzleavesl nearthe central portions thereof, forwardly of the springs IE4, are curved inwardly at l29; Fig.- 3, to .provide clearance for the fingers 'of the=operator in' placing the insole blanks upon the-leaves and-to facilitate removal of the matrix gafter lthevblanksmave been applied thereto.

The leaves 26 are closed by means of a solenoid f0;'"Fig.-3, having an armature I32 connected by a link M4 to one arm I36 of a bell crank lever i38=pivotedrat ifierto'the-plate -56. The other-arm M!) of the lever' carries a horizontally extendingpivot :rod Hi2 having ears 1% atrthe ends thereof. Extendingupwardly. through the ears *are bolts-M5. screw threaded to links 1'43 which: are pivoted-ati I59 00 bifurcated brackets l-52zsecured by rivets. lb lrtot'the lower central portions of the -.outer faces of the leaves :26. Springs J56 surrounding. the rods M5 between the links-4 18 and the ears Hit-are operative to force the leavesl.zdztowardc-each other under yielding pressure. when. the solenoid is: actuated.

*Initiation of operation of the solenoid is accomplished-by meansofa stud I62,"Fig. 3, on the sliding'member =58; the :stud being arranged when the member is depressed to. engage a screw laden" a lever-1166pivotedv at its on the bracket 16. Angulanmovement of the lever efiects: engagement with-a buttonv il'c of aswitch M2 for energizing the solenoid 13B.

"The: spotting mechanism above described is shown as mounted upon the insole pressing machine lfl'gwig. 1, which is provided with two pairs of pressure rolls, generally-indicated by reference character; 1 M, through which. a matrixwith in! sole blanks spotted 'rthereon can. be. passed in order permanently to bond together the blanks and canvas.

-It- 'is to be-understood that. the :matrix supports#22,"24x andxthe-rleaves 25 are" constructed the leaves-are closed .in the positions indicated by the dot-dash lines of Fig. 14,corresponding abutments'are. in 'alinernent. As a result, the insole-blanks are-supported by the leaves with their edges in horizontal alinement and lying inparallel vertical planes which are also parallel to the faces of the matrix.

*Prior'to assembling .arun of insoles ofithe same size, atypical matrix to which reinforcing material hasnot been applied isplaced upon the supports 22 and 24. The heel stop 56 leadjusted longitudinally of the frame'rmemberlfi by meansof the screw .18, and .the supports'22 and- 24 are adjusted heightwise of the. member by: screws '38 and 5B. These adjustments can be made withthe leaves'26 closed and with an -uncoated insole blank'ion one of them, the position of :thermatrix-being shifted until'it is centered-1relativelyntothe edges of the blank. In this connection-itisto be noted that the blanks usedwith a. particular matrix are. sufflciently larger than the matrix, .so-that-..th'eir marginal portions will extend beyond the matrix by A to inch. This provides allowance for trimming the assembled insoles to the contour of the matrix.

In operating the mechanism a pair of insole blanks are placed upon the leaves 26, Fig. 1, with the adhesively coated faces facing each other. Each blank is positioned with an edge resting on one of the abutments 96 and with forepart and heel part edge portions located behind the retaining members IIlD, the heel end portions being positioned against an abutment I20. A matrix I2 having canvas located upon its opposite faces is positioned on the supports 22 and 24 with the ribs 28 of the support extending into the groove 30 of the matrix, and with the heel end of the matrix in contact with the stop 65. The operator then exerts downward pressure upon the forepart of the matrix resulting in downward movement of the slide 48 which, through stud I62 and lever I66, actuates the switch button I'Hl causing an operation of the solenoid I30. The solenoid rotates the lever I38 in a clockwise direction applying pressure through the springs I56 to the leaves causing them to close. When the leaves approach the matrix the retaining members H0, through the action of links H2, are retracted permitting engagement of the insole blanks with the canvas. As the leaves are forced toward the matrix the leaf springs I24 press the foreparts of the blanks against the canvas with suflicient force to effect bonds over portions of the abutting adhesively coated surfaces.

The operator holds the forepart of the matrix depressed until the leaves have closed, then removes the matrix and the assembled insoles from the machine. As the forepart of the matrix is raised by sliding it upwardly past the springs I24, the spring 60 forces the support 24 upwardly efiecting a release of the switch button I and causing the current through the solenoid to be shut off with the result that the leaves are returned to their open positions under the action of the force of gravity which forces the lever I38 and its associated ports in a contraclockwise direction, Fig. 3.

Subsequent to the removal of the matrix it is passed through the rolls I'M which complete the bonding of the insole blanks with the reinforcing material.
